Born from the laptop the day, the debate about the battery has never stopped, because the use of persistence is very important to a notebook computer technology index, which determines the laptop battery capacity of notebook computers this important indicator. In the end how to use in order to maximize the effectiveness of the battery to extend battery life of it? Here, we will list all the types of errors we often vulnerable to: (without the instructions are for the most commonly used lithium-ion battery)
First, for the first time using the battery, the first three need to be charged 12 hours?
This is completely unnecessary. Because now the laptop has a good power management circuits and charge management system, when the laptop battery reached saturation, the control circuit will automatically switch to the off state, so long as full on the line, not to say that the longer you charge the longer you can use of.
Second, in order to prevent the memory effect, we should run out of power before charging it?
Discharge the battery before each charge is not necessary, but also harmful. They had proved: battery depth of discharge will be unnecessary to shorten the laptop battery life, it is recommended to use about 10% when the battery can be recharged while. Of course, when the battery power is still more than 30% is best when not charging, because the memory effect does exist.
Third, insert the AC, the battery should be seized, in order to prevent repeated charge and discharge it?
I’ll give you advice is: do not! Of course, you can take the natural discharge of lithium-ion battery to refute me, saying that the natural discharge of the battery, if there is access to power will be repeated charge and discharge, and reduce the battery life. And I give you “instead of” this answers the following reasons:
1 Now the notebook power control circuit design of this feature: that is, when the battery reaches 90% (such as HP’s most models) or 95% will be charged, but to achieve this through natural discharge capacity of a time for 2 weeks months, when the battery is idle for a month or so to fully charge and discharge in order to maintain battery capacity, this time you should be concerned about is the battery should be bit of exercise instead of being idle again after the charge.
2. Even if the battery “unfortunate” was once again charged, losses will not be long without the battery than the power drop caused by the large number.
3. Your data than you or your notebook batteries are much more valuable, a sudden power failure has not only hurt your notebook, can not restore the data is too late to regret.
Fourth, the long-term preservation requires fully charged battery is it?
Read the following to clear the table: (percentage of saturation at the time relative to the initial value)
Storage temperature of 40% state of charge 100% state of charge
0 98% (a year later) 94% (one year)
25 degrees 96% (a year later) 80% (one year)
40 degrees 85% (a year later) 65% (one year)
60 degrees 75% (a year later) 60% (3 months)
Obviously, if you want long-term storage batteries, dry and cold as much as possible on the environment and let the remaining battery power in about 40% is ideal. Of course, the best month to take the battery out with time, both to ensure that the battery a good state of preservation, they will not let the loss of damage to the battery power completely.
Fifth, how to use laptop as much as possible to extend the use of time?
1 to reduce the screen brightness. But power-hungry LCD screen, the brightness reduction can effectively extend the use of time.
2 Open SpeedStep and PowerPlay power-saving features such as. Now the notebook processors and graphics chips have lower operating frequency and voltage to extend the time of the function, open the options can greatly extend the battery life.
3 using hard drives and optical drive spin-down software: such as NERO DriveSpeed, PowerBooster other software can reduce the optical drive, hard drive speed, etc., can effectively reduce the notebook’s power.
4. You can see the laptop battery Lu master software details.
